IMPROVEMENT IN HYDROCARBON-BU P NE RS.

Specification forming part of Letters Patent No. 38,031, dated March 31, 1863.

To all whom, it may concern.-

Be it known that I, MILLs L. CALLENDER, of New York, in the county and State of New York, have made certain Improvements in Hydrocarbon-Burners; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The nature of my invention consists in providing hydrocarbon-burners with appliances by which the heat of the illuminating-flame is prevented from being communicated to the wick'tube and oil-receptacle, and by which the burner will burn hydrocarbon oils with a clean, smokeless flame, either with or without a glass chimney.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

Thedome b of the deflector A, as shown in FigureI of the accompanying drawings, is formed of metal, and is provided with the flame-slot c. The heat communicated to the dome b by the flame is confined entirely in the said dome b by the mica cylinder d, which is secured firmly to the dome b, and to the base f of the deflector A, by means of the flat coniformed rings 9 g and h h. The top of the mica cylinder (1 being clasped between the outer surface of the dome b and the inner surface of the flat coniformed rin g gg, and firmly secured in this position by punching aportion of the metal ofthe flat conil'orm ed ring gg, through the top of the mica cylinder d, into the metal forming the lower part of the dome b, as represented by the dots p p p in Fig. I of the accompanyin g drawings, the bottom of the mica cylinder cl is clasped between a metallic flange, rising from the base f of the deflector A, and the interior surface of the flat coniformed ring h h, and firmly secured by punching a portion of the metal of the flat coniformed ring h it through the bottom part of the mica cylinder cl into the metallic flange rising from the base f of the deflector A, as represented by the dots s s s in Fig. I of the accompanying drawings. The mica cylinder cl is thus firmly held between the dome b and the base f, and thus completely confines theheat imparted by the flame to the dome b of the deflector A.

The wicktube J of the burner K, as shown in Fig. II of the accompanying drawings, is provided with the interior adjustable metallic and mica deflector m, (shown in Fig. III of the accompanying drawings,) the deflector being so arranged that the flat surfaces of the mica shields 0 0 are presented to the sides of the flame, causing currents of air to be impelled in close proximity to the sides of the flame without imparting heat to the wick-tube J. The mica shields 0 o are movable, and can be changed or renewed at pleasure. By elevating the interior adjustable metallic and mica deflector m, the burner can be used withouta chimney, and by again depressing it a chimney can be applied and the burner used as the ordinary chimney-burner, with the great advantage of not communicating the heat of the flame to any portion of the burner or lamp, below the metallic dome b of the cone A.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. An improved lamp-deflector composed of a combination of mica and metal, consisting of a metallic base ring or flange, f, the mica or similar non-conducting cylinder cl, and insulated domeb, constructed as above set forth.

2. The use of a mica, glass, or similar nonconducting cylinder, when applied to a lamp top for the purposes above specified.

3. The method of securing the mica to the metal, as above specified.

4. Constructing the interior adjustable cone m of acombination of mica and metal, as above set forth.
